4 Claims. Cl. 294-17 This invention relates to pickaroons such as areused by loggers and the like for moving pulpwood and logs during loggingoperations.

Pickaroons have long been used by woodsmen as a convenient means forgripping logs for moving same. A Woodsman can readily roll, lift orslide a log if he has a good pickaroon to work with.

Pickaroons which are in common use, however, have one great drawback inthat their points break very frequently. The points must necessarily beslender in order to sink into the wood to provide the grip necessary forthe movement of the logs, and because of theirslenderness and the heavywork they are required to do they frequently break. Pickaroons breakmost frequently during the winter time at extremely low temperatureswhen wood is frozen solid. The metal seems to break more readily inextremely cold temperatures such as 20 and 30 below zero. When awoodsmans pickaroon breaks, he is severely handicapped and cannot workas efiiciently or safely as he can with his pickaroon. A Woodsmannormally carries only one pick'aroon, of course, because they are bulkyand he has other equipment to carry and he cannot carry a spare of allof his tools, and thus the breaking of his pickaroon causes him to behandicapped.

Pickaroons are conventionally made of a single: piece of metal andforged to shape so that when a point breaks, a new point must be madeeither by drawing out the metal of the old point and shaping same, whichresults in a shorter point; or, by making a new point and welding sameon to the old shank of the pickaroon. These are relatively costly andtime consuming operations for the points are normally hand forged by alumber camp blacksmith.

It is one of the principal objects of my invention to provide apickaroon having a removable point whereby a pickaroon may be quicklyrepaired if the point portion thereof should break. 7

Another object is to provide a removable point for a pickaroon which isrelatively small so that a spare can readily be carried in ones pocket,glove compartment of his vehicle, or on any vehicles which servicelogging equipment, or the like.

Another object is to provide a pickaroon and removable point thereforwherein the point may be quickly changed yet a sturdy connection isprovided between the point and shank of the pickaroon so that efliciencyof operation is not impaired because of shakiness of the removablepoint.

Another object is to provide means for securing a removable point on ashank of a pickaroon in a secure and easily removable manner.

Another object is to provide a tapered seat in a pickaroon shank toreceive a portion of the removable tip, the seat portion of theremovable tip being tapered similarly to the seat in which it isreceived to provide for a solid and secure seating of the point forproper frictioning of the tool.

ited htates Patet "ice Another object is to provide an opening throughthe shank of a pickaroon adjacent the inner end of the pickaroon pointto permit its being driven loose from its seat within the shank.

Another object of my invention is to provide a pickaroon having threemajor pieces for convenience of construction.

These and other objects and advantages of my invention will become moreapparent as the description proceeds.

In the accompanying drawing forming a part of this application Fig. 1 isa side elevational view of a pickaroon made in accordance with myinvention.

Fig. 2 is an end view of Fig. 1 with the point removed.

Fig. 3 is a perspective view of the removable point for my invention.

Fig. 4 is an edge view of Fig. 1.

Fig. 5 is a vertical sectional view of Fig. 1 showing the mounting ofthe point in the tool shank.

Fig. 6 is a broken side elevational view of a modified form of myinvention.

Fig. 7 is a vertical sectional view of the point portion of the toolshown in Fig. 6 to illustrate the mounting thereof.

In the drawing the reference numeral 1 indicates the handle for apickaroon which preferably comprises a conventional ax handle, or thelike. The tool shank 2 is fitted on the end of the handle 1 in aconventional manner.

The tool shank 2 is preferably made up of a sleeve portion 3 made offiat bar iron, or the like, and bent: to form an eye 4 to receive thehandle 1, see Fig. 4. The ends of the bar metal are bent together andwelded as at 55 to the tool receiving portion 6.

The tool receiving portion preferably includes a socket member 7 havingan elongated tapered seat 8 therein. The seat 8 is preferably circularin contour for convenience in manufacture, and is elongated so that ataper may be provided which will permit the secure seating of thetapered shank 9 of the tool point ltl.

The inner end of the socket or seat 8 is provided with a slot 11 toreceive the key portion 12 on the inner end of the tool point 10 toprevent the rotation of the tool point 10 within the socket 8.

The socket member 7 is preferably slit as at 13 and provided With a pairof wing-like projections or lugs 14 and 15, one on each edge of the slit13. The wing or lug 14 is formed integral with the portion 6 of the toolshank 3 and the Wing or lug 15 extends from the socket portion 7 but isseparated or free-floating therefrom as shown in the drawings so as toform, in conjunction with the Wing 14, a means to clamp or squeeze thesocket member 7 around the shank of the tool point 10.. A clamping bolt16 is provided to permit the clamping of the tool point 10 in the socket8, the tool shank having a cylindrical shape as at 30 and the socketbeing similarly shaped as at 31 in the area where the clamping takesplace to insure a firm grip on the shank. The clamping bolt has a lockwasher 17 thereon to prevent accidentally loosening of the clamping boltwhen the tool is in use.

As can be readily seen from the drawing, a point 16 may be readilyinserted in the socket 8 with the corre sponding tapers of the shank 9and seat 8 forming a solid seat for the point on the tool shank 3. Bytightening the clamping bolt 16 the point 10 is held securely inoperating position on the tool shank, and the key 12 prevents rotationof the tool in the shank.

If the tool point should be broken, it may be readily removed byloosening the clamping bolt 16 to release the grip on the tool at theareas 30 and 31 permitting the tool point to be removed.

In the event the tool point should become firmly seated in the socket 8because of long use of the tool before the point breaks, I have providedan opening 18 transversely through the shank 3 of the tool into whichopening the key 12 of the tool point extends, as shown in Figures 1, 5,6, and 7. This arrangement permits the tool point 10 to be 'driven looseby inserting another point, a screw driver, or any suitable instrumentinto the opening 18 to drive the tool point loose from its seat.

In Figs. 6 and 7, a modified form of my invention is shown wherein thetool receiving portion 6 is provided with an externally threaded portion19, to receive an internally threaded nut 20. The portion 6 is providedfor an internal tapered seat 21 corresponding to the seat 8, and thetool shank '9 is similarly tapered to be received in the seat 21. i

The tool point 10 is preferably provided with an opposed taper 22extending from the tapered portion 9 in the opposite direction or towardthe point 23 of the tool. The nut 20 has a tapered seat 24 whichreceives the tapered portion 22, and by tightening the nut 20 thetapered portion 9 is securely seated in the socket 21.

The removement of the nut 20 will permit the tool point to be removed inthe same manner as above described.

The above described structure will overcome the disadvantages inconventional pickaroons, and will provide for greater convenience andefliciency for woodsmen handling logs.

Having thus described my invention, what I claim is:
